Grammarly is the best-known English writing assistant. Wherever you write (email, Google Docs, Word, LinkedIn, web forms), it underlines spelling, grammar and punctuation mistakes and suggests fixes. Newer versions also use generative AI to rewrite sentences, make the tone more formal or friendly, and shorten text. The company that makes it has renamed itself Superhuman, but the product is still sold as Grammarly. Its main advantage over chatbots is that you don't have to copy your text anywhere; it works exactly where you type.

What is Grammarly good for?#

  • Business email in English: A developer or freelancer writing to a client abroad catches small mistakes and unclear sentences before sending.
  • English papers and theses: A student finds grammar errors and repetition before submitting a paper to a journal.
  • Resumes and cover letters: A more formal tone and clearer sentences for a job or admissions application.
  • Learning while you write: The short explanation for each fix helps you recognize your own recurring mistakes.
  • English site content: A shop writing product descriptions for an international market makes the text smoother and more professional.

Strengths and weaknesses#

Strengths:

  • It is everywhere: a browser extension, desktop app, mobile keyboard and Word add-in.
  • It is accurate and dependable at catching English spelling and grammar mistakes.
  • The free version is genuinely enough for basic needs.
  • The explanation of each fix is useful for learning.

Weaknesses:

  • It doesn't support languages other than English.
  • Its suggestions can make writing uniform and styleless; don't accept them blindly.
  • Your text goes to the company's servers for processing, so be careful with confidential writing.

Free version and pricing#

Grammarly has a permanent free plan that covers spelling, grammar, punctuation and basic tone detection, plus a limited number of generative AI requests. The paid subscription adds full sentence rewrites, style and clarity suggestions, plagiarism checking and a larger AI quota. There are team plans too. Check the official site for current prices.

Language support#

Grammarly works in English only and gives no suggestions on text in other languages. For non-native English speakers its use is writing in English, not editing in your own language.

Getting started in three steps#

  1. Sign up with your email and install the browser extension or desktop app.
  2. In settings, choose your English variety (American or British) and the goal of your text.
  3. While writing, read the suggestions one by one and accept only those that keep your meaning.

Grammarly alternatives#

  • QuillBot: stronger at paraphrasing and summarizing, with a simpler grammar checker.
  • DeepL: if you think in your own language, its fluent translation into English and its text-improvement feature help.
  • ChatGPT: for full rewrites with a precise instruction, in any language.
  • Claude: for editing long texts and preserving the author's tone, in English and other languages.

For editing text in a language other than English, editing and rewriting text with AI explains a practical method.
